The model was found by her husband slumped over a bed, with one leg tucked underneath her and the other hanging down to the floor.

Peaches, 25, is likely to have died from an overdose of the Class A drug just like her mum Paula Yates, an inquest heard.

Police are now urgently trying to find the person who supplied her with the fatal stash.

And they are also looking to solve the mystery of why no drugs or drug paraphernalia were found at the death scene.

Heroin is usually ­heated up and injected with a syringe or smoked on aluminium foil.

But none of those materials was found, ­suggesting someone may have covered up the evidence before fleeing.

Peaches’ shocked husband Tom Cohen, 23, discovered her body in the spare bedroom of their detached country house after spending a normal weekend apart, the inquest heard.

“All of the friends and family who had contact with Peaches during this period described how she seemed her normal self”

Det Chief Insp Paul Fotheringam

Rock vocalist Tom had taken their sons Astala, two, and 11-month old Phaedra to stay with his parents in south-east London, leaving Peaches at home in Wrotham, Kent.

She spent Friday night out with friends and then kept in touch with her family on the phone on Saturday April 5. Tom’s dad Keith took Phaedra back home on Sunday and spent half an hour with Peaches before leaving. She was found dead the following day.

Det Chief Insp Paul Fotheringam said she seemed her normal self and had even booked a family day out for the following weekend.

He told the hearing: “It is believed that Peaches spent Saturday afternoon, into the evening, and Sunday morning at her home address alone.

“Throughout this period she maintained telephone contact with family and friends.

“Peaches maintained contact throughout Sunday and at 5pm Thomas’s father Keith Cohen took Phaedra back to Wrotham and spent half an hour with Peaches before leaving the child with her.”

Peaches’ last contact with anyone was on Sunday evening at 7.45pm when she spoke with a pal on the phone.

Mr Fotheringham went on: “All of the friends and family who had contact with Peaches during this period described how she seemed her normal self and was making plans for the future, including a family outing for her sons for the following weekend.”

But the next day Tom could not get hold of his wife and dashed back home where he made the grim discovery at 1.30pm.

Mr Fotheringham added: “He entered the property and went upstairs, thinking his wife may be asleep.

“He entered the spare bedroom where he found her, obviously deceased, on the edge of the bed with one leg hanging down and the other tucked underneath her.”

Son Phaedra was in the house when his mum died.

Peaches’ body was taken to a mortuary where her rock star dad Bob Geldof had the heart-wrenching task of formally identifying his daughter.

Toxicology tests confirmed the level of heroin in her body was “likely to have played a role in her death”.

The revelation threatens to tarnish Peaches’ image as the perfect celebrity mum.

The TV presenter was a champion of “attachment parenting” where mums and dads spend more one-on-one time with their kids, including sleeping in the same bed. But insiders say there were signs her world was beginning to unravel.

Peaches, who had a history of drug use, had moved to the country in an attempt to escape the London party scene.

There was a also a rift with dad Bob, 62. Peaches had accused her father of showing no interest in his grandchildren.

Friends became alarmed when she flooded Twitter with thousands of photos of her kids days before her death.

Hours before her death, Peaches posted a pic of herself as a tot with mum Paula who died from an accidental heroin overdose in 2000, aged 41.

Last night fans jumped to Peaches’ defence on Twitter.

Singer Cheryl Cole, 30, wrote: “The world might be a better place if we tried understanding people’s reasons rather than judging their actions.”

Kent Police confirmed they are investigating who supplied Peaches with the fatal drugs.

The five-minute inquest hearing in Gravesend was adjourned. A full inquest will be held on July 23.

Bob Geldof is to marry his French actress girlfriend Jeanne Marine, 48, after 18 years together. Close friend Jerry Hall, 57, said: “They have been through hell but they are determined something positive will come out of it.”
